[GIT PULL] SCSI fixes for 3.0-rc1

[James Bottomley]

This is a single fix for the queue refcounting oops we were debugging
just before 3.0-rc1 was released.  Jens is still working on the DEAD
queue guard bit.

The patch is available here:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git

The short changelog is:
